That cam sounds more aggressive than the GM HO crate cam....212/222 @ .050" is pretty mild.
What is the idle set at? How much base timing? Where is the vacuum advance hooked up to...ported or manifold source? How much vacuum at idle?
I'll get a video of my buddy's '65 the next time I'm near his car. Slightly noticeable lope at idle but clears right up off idle.
Are you sure that's a stock GM HO cam??
